Radisson Announces Additional Assays from 2024 Drill Program at O'Brien

Feb 26, 2025


Radisson Mining Resources Inc. has announced additional drill assay results from its 100%-owned O'Brien Gold Project ("O'Brien" or the "Project") located in the Abitibi region of Québec. 

The seventeen drill holes reported were completed as part of the 35,000 metre, 2024 drill program designed to increase the scope of gold mineralization at the Project with a combination of deep and shallow drill holes. Prior to the end of last year, Radisson released the results of several deep drill holes which demonstrated high grade mineralization at substantial step-outs below the base of the current Mineral Resource and below the historic O'Brien Mine workings (see Radisson News Releases dated September 24, 2024, October 30, 2024 and December 16, 2024). Today's results represent shallower drilling at the margins, or within, the existing Mineral Resource over the Project's "Trends 1, 2 and 3". The new data continue to demonstrate the Project's characteristic narrow and high-grade gold mineralization within quartz-sulphide veins. 

Results Highlights: 

  • OB-24-358 intersected 8.36 grams per tonne ("g/t") gold ("Au") over 15.0 metres within a broad mineralized interval with multiple veins, including 56.0 g/t Au over 1.0 metre and 41.1 g/t Au over 1.0 metre; 

  • OB-24-327 intersected 10.32 g/t Au over 4.1 metres including 18.30 g/t Au over 1.5 metres;

  • OB-24-350 intersected 46.40 g/t Au over 1.0 metre;

  • OB-24-339 intersected 10.05 g/t Au over 1.3 metres; and

  • OB-24-351 intersected 9.89 g/t Au over 2.9 metres including 17.90 g/t Au over 1.4 metres

Matt Manson, President & CEO, commented: "We are reporting today results from drill holes completed during the fall as part of our 2024 drill program. They demonstrate the type of narrow high-grade intercepts within broader mineralized envelopes that are so characteristic of the O'Brien Gold Project and serve to fill out our interpretation of mineralization in and around the existing Mineral Resources. Our drilling priorities in 2024 represented a balance between shallower targets within the existing Mineral Resource model, and deeper step-outs geared to new discovery. The deep step-outs greatly exceeded our expectations. They included the deepest hole ever drilled at the Project, OB-24-337, which returned 31.24 g/t Au over 8 metres a full 500 metres beneath the historic mine workings, and OB-24-324 which returned 27.61 g/t Au over 6.0 metres 170 metres beneath the base of our "Trend #1". The results for these deep drill holes were prioritised in the laboratory, so as to guide planning for the 2025 drill program, which is almost exclusively aimed at extending O'Brien's gold mineralization to depth as well as following up on the recently re-discovered "Jewellery Box" zone. The 22,000 metre 2025 drill program is proceeding well with three rigs at site with a steady flow of results expected."

Gold Mineralization at O'Brien

Gold mineralizing quartz-sulphide veins at O'Brien occur within a thin band of interlayered mafic volcanic rocks, conglomerates, and porphyric andesitic sills of the Piché Group occurring in contact with the east-west oriented Larder Lake-Cadillac Break ("LLCB"). Gold, along with pyrite and arsenopyrite, is typically associated with shearing and a pervasive biotite alteration, and developed within multiple Piché Group lithologies and, occasionally, the hanging-wall Pontiac and footwall Cadillac meta-sedimentary rocks.
